ATOMIZER.

Application filed December 13, 1922.

To all 'to/10m t may concern.

Be it known that l, LoUIs l-lnNRr Lnnlirr BELLEN, a citizen of the Republic of F "ance, and resident of Neuilly-sur-Seine, France (post-ollice address Rue du Lieutenant Boncour), have invented a new and useful Atomizer, which improvements are fully set forth in the following specification.

The object of my invention is to provide an atomizer device designed toV feed with liquid fuel four cycle explosive engines, in which the first cycle or stroke causes a vacuum, as those of the Bellem et Bregeras type.

My atomizer is intended to be intercalated between the engine and a distributer pump of the type described in the application filed in France for the Bellem et Bregeras patent.

In order to make my invention more clearly understood l have illustrated, as an example, a practical embodiment thereof in and by the appended drawing herein.

Figure 1 is a longitudinal section of any atomizer constructed according'to my in vention. 4

Figure 2 is a cross section according to line o-fc of the grooved cylinder secured in the hollow stemmed valve.

My atomizer is essentially constituted by a valve fitted with a hollow stem 1 in which is secured, by a cross pin 2, a. cylinder 3 provided with grooves l arranged 011 any suitable manner, as for instance according to. the generating liner or helicoidally.

Said grooves are interrupted from place to place by circular recesses 5. The pin that holds cylinder 3 in place cannot become displaced since held in position by cross piece 6.

Hollow valve 1 is closed at its lower part by a plug 7 in which are cut grooves S the number and size of which depend on the quantity of fuel to be atomized.

Said part is secured on the valve and its grooves 8 correspond to holes 9 bored in the valve at right angles to the grooves.

In line with those grooves 8, holes 10, inclined therefore 150 like the valve seat, are bored through the wall of hollow valve stem 1.

The lower grooves of part 8 are located just opposite holes 10, it being understood that there are as many holes 10 as grooves 4l.

At its upper part, member 3 has also grooves which are more or less long and Serial No. 606,761.

wide according as there is more or less fuel to be atomized.

A In recess 5 loca-ted immediately under said grooves holes 11 open out bored lat 45 through the hollow valvestem. Said holes.

receive air coming from holes 12 of cross piece 6 and grooves 13 of guide 14. Cross piece 6 is provided at its lower part with grooves 15 and block piece 16 a-Oainst the conical head of the hollow valve. @aid piece 16 has grooves 17 and is dog-secured on the yglve cone so that holes 9'open on grooves Members 6, 14; and 16 are blocked on the valve by a split nut 18 screwing on the upper threaded end of the hollow valve stem and prevented from untightening by a set screw 19.

' The foregoing parts are therefore mounted, as shownby Figure 1, on the engine valve buffers 20 or at any other preferred place. i

A. spring 21 returns the valve to its seat 22. A cap 23 screwing on body 20 is provided with holes 24C permitting air to enter chamber`25. A damper 25 is adapted to be operated on starting so as to close holes 211' and create a depression that will suck in fuel through pipe 26 independently of any other feeding device, feeding being effectuated mechanically during operation.

The same result would be obtained by omitting damper 25 and arranging around tube 26 a solid washer working freely on said tube and resting through gravity on the top of the hollow valve. 0n starting, the vacuum created by engine suction in the hollow valve vclosed by the said washer would produce a fuel intake, and once under way, fuel would be pump delivered.

Operation is as follows. The atomizer is mounted on an engine the air valve of which opens only about the end of travel, on the pistons downstroke, the atomizer being automatic, opens and its valve assumes the position shown by Figure 1. At this moment fuel is fed to the atomizer by a suitable adjustable delivery pump connected with the atomizer by a conduit. Air emulsiiied fuel then passes into the upper grooves. Flow through these is elfectuated under weak depression since there is an air intake through holes 11. This is intended to permit the quantity of fuel required for an explosion to be stored in the upper grooves, said quantity being kept up by capillarity and exhausting at one flow when the atomizer valve opens since air holes l1 prevent a, sudden suction of fuel. v

As soon as fuel and air have gone beyond first recess 5 the air and fuel emulsion circulates in the baille arranged grooves until, through the lower grooves of member. a violent air-blast coming from holes l0 continues the atomization already taking place in vacuum space 28. Produced fuel sprays issue through holes9 an-d are violentlyv shattered by a. very fast air blast rushing through grooves 17 ofniember land coming under the depression produced by the pistons downstroke. Vers is well known, sprays being produced in vacuum are most minutely atomized, resembling mist or smoke.

- lt should be plainly understood that my atomizer as above describe-d is given, only as an example and that l reserve every right to make any constructiona-l modifications without departing from the scope of my invention.

Having now particularly described and ascertained the nat-ure of my said invention as well as the manner in which the saine is to be performed, I declare that what I claim is:

l. An atomizer for feeding four cycle explosion engines, creating a vacuum on the first cycle or stroke; such atomizer being constituted by a hollow-stemmedv conicalheaded valve, the stem and head of which are holed with suitable air inlets; a grooved plugsecured on the lower end of the valve and the grooves of which are opposite the valve head apertures; a cylinder provided with grooves and recesses and located inside the hollow stem; two successive jackets surrounding the hollow stem and provi-ded with air passage grooves, a grooved guide blocking ,said jackets on the valve head; a nut screwing on the upper portion of the hollow stem and compacting the whole as unit; a body secured to the engine and within which said unit slides; an antagonistic spring keeping the valve on the latters seat; and a cap having air inlet holes adapted to be closed by a damper;

2. An atomizer for fee-ding four cycle eX- plosion engines, creating la vacuum on the first cycle, or stroke, comprising a hollow stemmed conical-headed valve, the head and stem of which are provided with suitable air inlets, a. plug secured vin the lower endy of the valve and provided with grooves registering with the valve head air inlets, a cylinder located within said hollow stem provided with a plurality of grooves parallel to its generating line' vand alternating with annular grooves, jackets surrounding the hollow stem and provided with air pas-V
